QUESTION- What caused the 8:46:30 seismic event 10 seconds before the aircrash?
ANSWER- The only possibility: HUGE EXPLOSION(S)!

Notes:
Ginny Carr audiotape ~9.2 second gap between initial explosion and aircrash.
The 9/11 Commission avoided the time of the initial seismic event.
The 9/11 Commission avoided many witnesses who testified of explosions in the basements.
NIST avoided many witnesses who testified of explosions in the basements.
NIST avoided 9/11 Commission’s time.

Demand new 9/11 investigation now, this time ONE WITH TEETH!
Justice waits.

one of just way too many questions that americans with some semblence of an iq should be asking themselves about 9/11.

why there was no immediate air cover by our military over our nations capitol when it was clearly apparent for well over an hour that we were under attack.

what REALLY happened to the plane that went down in shanksville pa?
if the plane was in fact forced down by the passengers, where is/was the wreckage from the bulk of the fuselage? countless comparative photos and videos of the same exact models of the plane that crashed in pa show much or most of the wreckage in the same type of crash incidents.
yet in shanksville there was nothing.

evidence gathered from the "crash" site has one chunk of an object that weighed more than 800 pounds that was approximately 1 mile from the crash site.

it's physically impossible for an object that size to bounce over or through the rough terrain that is like the one in pa.

answer- the plane was blown out of the sky by our own military.

so it's questions like these and the ones surrounding the twin towers that cast a great deal of doubt as to what actually happened on the morning of 9/11 and what was finally spun into the neocon schtick that ennded up as the koolaid that many unwittingly consumed.
